Iron assimilation in Cryptococcus neoformans.

Abstract excerpt

We studied the effects of iron chelators and of a thallium salt on growth of Cryptococcus neoformans in defined medium. An oxidant-sensitive mutant strain was found to require exogenous ferric iron for growth. Using this strain, we found that the synthetic iron chelator, N-hydroxyethylenediamine triacetate (HEDTA), in several saturation states, stimulated growth as well as the comparably saturated siderophore...
